How DCO Works
When you enable DCO on an ad set, you provide multiple creative elements: up to 10 images or videos, 5 text variations, 5 headlines, 5 descriptions, and 5 CTA buttons. Meta's algorithm combines these into hundreds of possible ad variations and dynamically serves the combination predicted to perform best for each user. The system learns which combinations work for different audience segments, placements, and contexts. Unlike A/B testing individual ads, DCO tests at the component level, identifying winning elements faster with less budget.
